Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a gas-liquid separator for separating ozone gas and ozone water in an ozone water generator.

[0002]

2. Description of the Related Art Generally, an ozone water generator dissolves ozone gas in tap water or the like to generate ozone water, and ozone water discharged from the ozone water generator is used for hospital medical equipment, vegetables, fruits and the like. It is used for washing, disinfecting, deodorizing fresh foods, kitchen equipment, tableware, etc. Although ozone water is effective for disinfection and deodorization, it is said that ozone gas is not desirable for health, so after dissolving ozone gas in tap water etc., excess ozone gas and ozone water And only ozone water needs to be discharged.

For this purpose, the ozone water generator is provided with an ozone water tank 20 as shown in FIG. 10, and the ozone water tank 20 stores a gas-liquid mixture of ozone gas and water. Then, the ozone gas is decomposed and released into the atmosphere, and only ozone water is discharged. Therefore, a water flow guide tube 21 is formed in the ozone water tank, and the ozone gas and the ozone water gas-liquid mixed water flowing inside are swirled and moved downward to move to the discharge port 22. . Since the pressure inside the ozone water swirl decreases, the light ozone gas bubbles 23 enter the inside of the swirl, and eventually rise due to their buoyancy and move to the decomposition device side.

[0004]

However, when such a natural-separation type gas-liquid separator is used, the ozone water tank needs to be high. The reason for this is that if the tank is low, the air bubbles are likely to be caught in the water stream and drawn into the discharge port 22. If the ozone water tank is large, gas-liquid separation can be performed relatively efficiently, but when trying to make the ozone water tank compact, the ozone gas bubbles are caught in the flow of ozone water before rising. And is easily discharged from the discharge port 22.

It is an object of the present invention to provide a gas-liquid separator for an ozone water generator which can solve the above-mentioned problems and reduce the size of an ozone water tank and efficiently separate ozone gas and ozone water. Make it an issue.

[0006]

In order to solve the above-mentioned problems, a gas-liquid separation device in an ozone water generator according to the present invention comprises an ozone water storing ozone gas generated by an ozone generator in a state of being dissolved in water. In an ozone water generator equipped with a tank, an inlet for gas-liquid mixture of water and ozone gas is formed at an upper part of the ozone water tank, and a discharge port is formed at a lower part. A gas-liquid mixture is swirled into the upper part of the inner cylinder from the inflow port and flows into the upper part of the inner cylinder. An exhaust hole for ozone gas is formed in the upper lid of the inner cylinder. A discharge hole for ozone water in the inner cylinder is formed at a lower end of the inner cylinder in contact with the bottom of the inner cylinder.

Preferably, a projecting edge is formed at the bottom of the ozone water tank so as to surround the outside of the inner cylinder.

It is desirable that the discharge port of the ozone water tank is formed along the spiral direction of the vortex.

Further, it is preferable that the lower end of the inner cylinder is closed by an inverted conical bottom lid, and the ozone water discharge hole is formed at the upper end edge of the bottom lid.

In addition, instead of forming the inflow port of the gas-liquid mixed water at the upper part of the inner cylinder, it is formed at the lower part of the inner cylinder, and the discharge hole for discharging the ozone water in the inner cylinder is formed. Instead of being formed at the lower part of the inner cylinder, it may be formed at the upper part of the inner cylinder.

FIG. 1 is a schematic diagram of an ozone water generator according to the present invention. The ozone water generator main body 1 has the same structure as a known ozone water generator, and includes an ozone generator (ozonizer) 1, an ejector 4 arranged in the middle of a water supply pipe 3 from a water tap 2, and an ejector 4. The ozone water tank 5 for separating the excess ozone gas from the ozone water after mixing and dissolving the ozone gas in the tap water by sucking ozone when passing the tap water through the water, and the processing device 6 for processing the separated ozone gas And a discharge hose 7. The ozone gas generated by the ozone generator 1 is sucked by the ejector 4, mixed with the tap water and stored in the ozone water tank 5. It is decomposed and discharged to the atmosphere, and the ozone water is discharged by a discharge hose 7 and used for use.

As shown in FIG. 2, the gas-liquid separator is located inside the ozone water tank 5 (not necessarily at the center).
, An inner cylinder 10 whose upper end is closed by an upper lid 11 is disposed.
The water supply pipe 3 is opened at the inflow port 8 at the upper part of the inner cylinder 10, and an ozone gas exhaust hole 13 is formed at the upper lid 11 of the inner cylinder 10.
An ozone water discharge hole 14 is formed at the lower end of the nozzle 0, and a discharge port 9 is formed at the lower part of the ozone water tank 5. The lower end of the inner cylinder 10 is in contact with the bottom of the ozone water tank 5. The water supply pipe 3 is, as shown in FIG.
It is arranged at a position eccentric from the center of 0. For this reason, the water flow of the gas-liquid mixed water flowing from the inlet 8 is
It flows like a swirl inside zero.

The processing unit 6 is usually filled with a catalyst,
Ozone gas is decomposed while moving through the catalyst and is discharged to the atmosphere.

According to the above configuration, the ozone gas generated by the ozone generator 1 is sucked by the ejector 4 and mixed with the tap water, and flows into the inner tube 10 of the ozone water tank 5 from the inflow port 8 through the water supply pipe 3. . The gas-liquid mixed water that has flowed into the inner cylinder 1
After flowing in the tangential direction of the inner surface of the inner cylinder 10, it extends downward while spiraling around the outer peripheral surface due to centrifugal force, and is further discharged from the lower end discharge hole 14 to the outside of the inner cylinder 10 and stored there. It is discharged from the outlet 9 by the discharge hose 7.

By the way, the gas-liquid mixed water swirls to cause a separating action by the stretching force, and the bubbles a of the ozone gas having a small mass are collected at the center of the swirl. Further, the ozone gas collected at the center floats above the ozone water by buoyancy, is discharged from the exhaust holes 13, and is carried to the processing device 6. The ozone gas is decomposed by the processing device 6 and discharged to the atmosphere.

The cross section of the vortex in the inner cylinder 10 has an inverted triangular shape, and the bubble a of the ozone gas drawn inside the vortex is located far from the ozone water discharge hole 14. For this reason, it is hardly possible to go out of the ozone water discharge hole 14.

Furthermore, the swirling flow of the ozone water occurs within a small area in the inner cylinder 10, and the smaller the vortex, the better the gas-liquid separation performance.

Preferably, the diameter of the inlet 8 is R1,
Assuming that the hole diameter of the ozone gas exhaust hole 13 is R2 and the hole diameter of the ozone water discharge hole 14 is R3, it is preferable that R1 be equal to or larger than R3, and that R3 be considerably larger than R2. As a result, the internal pressure of the inner cylinder 10 increases, the spiral state is improved, and the gas-liquid separation ability is improved.

As described above, since the ozone water and the bubbles a of the ozone gas contained therein are reliably separated in the inner cylinder 10, the height of the ozone water tank 5 does not need to be too high, and the ozone water tank 5 is made compact. be able to.

In FIG. 4, the inner cylinder 10 is disposed so as to be close to one side of the ozone water tank 5, and a projecting edge 15 is formed at the bottom of the ozone water tank 5 so as to surround the outside of the inner cylinder 10. It is an example.

According to this configuration, the bubble a should be
5, the bubble a rises beyond the protruding edge 15 before flowing into the discharge port 9 side as shown in FIG. At the time of this rise, buoyancy is applied and the bubble a rises. Therefore, the height of the protruding edge 15 is preferably higher.

The inner cylinder 10 may be arranged at the center of the ozone water tank 5, and a circular protruding edge 15 may be wrapped therearound.

Next, FIG. 6 shows the discharge port 9 of the ozone water tank 5.
Are formed along the spiral direction.

According to this, the ozone water discharged from the discharge hole 14 of the inner cylinder 10 flows into the discharge port 9 while rotating in the same winding direction. As described above, the vortex having the same winding direction is formed on the inner side and the outer side of the inner cylinder 10, thereby increasing the centrifugal force. When the bubble “a” is discharged from the exhaust hole 13 of the inner cylinder 10, as shown in FIG. As a result, the bubbles a collect on the outer surface of the inner cylinder 10, and the collected bubbles a become larger, the buoyancy increases, and the bubbles a rise. Therefore, gas-liquid is well separated.

FIG. 8 shows an example in which the lower end of the inner cylinder 10 is closed by an inverted conical bottom lid 16 and the ozone water discharge hole 14 is formed on the upper edge of the bottom lid 16.

According to this configuration, the gas-liquid mixed water is supplied to the inner cylinder 10
It creates a vortex inside and extends downward, but the bottom is in the shape of an inverted cone, which increases the centrifugal force but also increases the pressure. For this reason, the vortex cannot extend downward, but is formed at the upper part of the inner cylinder 10. Since the ozone gas bubbles are drawn into the inside of the vortex, the bubbles a also collect at the upper part of the inner cylinder 10. Therefore, only the ozone water is discharged from the discharge hole 14, so that the gas-liquid separation ability is improved.

Next, FIG. 9 shows that the inlet 8 for the gas-liquid mixed water is formed in the lower part of the inner cylinder 10 and the discharge hole 14 for discharging the ozone water in the inner cylinder 10 is formed in the upper part of the inner cylinder 10. This is an example.

According to this configuration, the gas-liquid mixed water flowing from the inflow port 8 moves upward while swirling, and the bubbles a of the ozone gas in the mixed water also move upward. Then, the ozone water is discharged to the outside through the discharge hole 14 on the upper part of the inner cylinder 10. Even if air bubbles a are mixed in the discharged ozone water, the air bubbles a scatter from the surface of the ozone water into the air due to their buoyancy, so that only the ozone water flows into the discharge port 9. Also, the bubbles a in the inner cylinder 10 are exhaust holes 13, 1
It is discharged from 3a. Therefore, gas-liquid is well separated.
